【千律】C++基础：子类的构造函数和析构函数

#include 
using namespace std;

class CRoom
{

public:

	char* name;
	int number;

	//  设置价格
	void SetPrice(int t_price)
	{
		price = t_price;
	}

	//  获取价格
	int GetPrice()
	{
		return price;
	}

	// 构造函数
	CRoom(const char* t_name, int t_number, int t_price)
	{
		int len = strlen(t_name);
		name = new char[len + 1]{ 0 };
		memset(name, 0, len + 1);
		strcpy(name, t_name);

		number = t_number;
		price = t_price;
	}

	// 析构函数
	~CRoom()
	{
		delete[] name;
	}

private:
	int price;
};

class CStarRoom : public CRoom
{
public:
	int star;

	// 子类构造函数
	CStarRoom(int t_star) : CRoom("HuiCui", 9999, 9999)
	{

	}
};

int main()
{
	// 对象初始化
	CStarRoom room(5);

	// 输出结果
	cout << "酒店名字：" << room.name << endl;
	cout << "酒店价格：" << room.GetPrice() << endl;
	cout << "酒店房号：" << room.number << endl;
	cout << "酒店星级：" << room.star << endl;
